Hard cast .357 and W296

[marcodo]

I would like to load hard cast 158gr SWC using up some w296 that I have left over. Looking for some hotter loads just for fun. I am having trouble finding lead data for this.

Perhaps I shouldn't be using lead. I also have 158 gr jacketed HP that might be better.

I understand W296 is touchy and should not be underloaded.

I also only have small pistol...not magnum primers.

Anyone with some thoughts and data input?

I suspect most will tell me to use another powder. I also have W231 and titegroup but was hoping to use up the W296

Thanks!

No reason not to use 296 with cast bullets but in my opinion you need magnum primers. There are those that load 296 with standard primers without issue though.

Just use Hodgdon 158 jacketed starting loads and go from there. http://data.hodgdon.com/main_menu.asp

Here ya go , it`s for heavier boolit but should give ya a starting point .

WW296=H110 , been the same for `bout 5yrs. now

Day before yesterday I loaded 15.0 grs. of H110 (Same as WW296) over a 358429 HP bullet (168 gr). Ran right at 1200 fps out of my 4" Security Six. Tried to do an expansion test with water filled jugs but the darn thing penetrated about 3' of them and STILL exited!!
This a plain-base bullet but I figgered out a way to apply a gas check. No leading.

I use 17 grains. Started with 15 and it was kind of wimpy.

Thanks guys. Appreciate the input
Seems like there is a pretty big range that is being used.
I think I will start with 15 grains.
What do I need to worry about if I use only standard primers?

Nothing. I use standard primers in everything except 454 Casull. Switched because I pierced a primer with a hot load. 454 runs at about 50% higher pressure than 357 so I wouldn't worry about that.

If you use a standard primer make sure you have a heavy crimp. Heck, with that powder you should make sure you have a heavy crimp anyway.
